I guess another professor felt the need do outdo
Professor Bitcorn, the Boston University professor who predicted that Bitcoin would fall to $10. I wonder what name the community will give to Roubini.

Fun facts: Apparently, this guy predicted the housing bubble crash of 2008 and he's been warning of various financial bubbles for years. He's known as "Dr. Doom."
He might get his predictions right once in a while, but that is more due to chance rather than anything else. Predicting a crash in an asset class is completely different from predicting that an asset class will go to zero. Posterity will make him a laughing stock, but at least he has got the guts to stick his neck out and state his views.
